A Denver judge Monday postponed the preliminary hearings of Amanda Deleon and Calvin Pitts, whose infant son died in June, to await toxicology reports on both parents.

Three-month-old Sanai Deleon-Pitts suffered numerous abrasions, fractures and burns — including a burn to the sole of his foot from a lit marijuana cigarette — before he died June 11.

Deleon, 21, and Pitts, 28, face felony charges of child abuse causing serious bodily injury. Both have admitted to using marijuana and have drug charges on their records.

Pitts, who is free on bond, and Deleon, who is still in custody, next appear in court Aug. 15.

The Denver district attorney’s office has said it’s waiting for the coroner’s report on Sanai to determine whether there will be additional charges.

A search-warrant affidavit for the couple’s South Federal Boulevard apartment suggests Sanai had started crying about 6 a.m. June 11 and Pitts found him unresponsive in his bouncy chair about 8 a.m.

“Ms. Deleon claimed she had never seen (Pitts) strike the victim. Ms. Deleon did confirm that (Pitts) punched a hole in her bedroom door after getting frustrated by the victim’s crying,” Denver Detective Ken Klaus wrote in the affidavit.

Authorities told Deleon that the hospital staff found a possible fracture to the right side of the baby’s skull and a separated right shoulder, but Deleon could not explain those injuries.

Sanai also had a second- or third-degree burn on the back of his left thigh as well as a fracture to his left femur, according to the affidavit.

Deleon told police that when she moved the baby about two weeks before his death, he let out a little cry and the leg swelled the next day.

Pitts told detectives he microwaved a wet washcloth for two minutes and wrapped it around his son’s leg to ease the pain, causing the burn. He later tried to dress it with antibiotic cream and bandages, he told authorities.

The other injuries — an abrasion under Sanai’s chin, tears inside and around his ears, a wrist fracture — couldn’t be explained, Klaus wrote in the search warrant.

The owners of Boulder’s Sterling University Peaks apartments, who this summer were cited for illegally subdividing 92 bedrooms in the complex, have reached an agreement to settle the case for $410,000, the city announced Thursday.
